May have jumped the ghost shrimp gun!

Ok so, I have a 55g community/semi aggro tank with:
5 tiger barbs (2 larger 3 small)
4 zebra loaches (small)
2 mollies (large)
...

Well, I took receipt of them before they touched a tank which is I'm assuming where most of the disease is. But I also didn't buy them as snacks. The barbs aren't really actively messing with them from what I've seen but who knows. There are plenty of great hiding places for them in my ferns, crevasses and caves but they roam around all willy nilly. I would assume they would be in hiding if they were in danger, no?
